ATM Chip Database

ATM Interface Module

Support for the chip includes backpressure handling of input data.
It optimizes the scheduling of data to the switch by incorporating three
priority-based backpressure queues, each for a different QoS. ATM Interface
Module generates a backpressure signal for the Receiver chip, as required.

A microprocessor interface is provided for control purposes.
As the traffic allows, the ATM Interface Module forwards extracted control
cells to the card's General Purpose Processor or inserts control cells (with AAL5
segmentation) from the microprocessor.

Multiple ATM Interface chips can be included to support high-speed/high-performance
16 x 16 Switch-on-a-Chip configurations.
